PU Foam Spray Insulation Bangladesh

Spray Polyurethane Foam (SPF)

Spray polyurethane foam (SPF) is a two-component, liquid-applied insulation system that expands on contact to fill all gaps and voids, creating a seamless, airtight thermal and moisture barrier. It is one of the most effective insulation systems available for roofs, walls, cold stores, and industrial buildings in Bangladesh.

💡 SPF has an R-value of R-6 to R-7 per inch — significantly higher than fibreglass batts or rigid foam boards, making it the most efficient insulation per unit thickness available.

Frequently Asked Questions

What is the R-value of PU foam spray insulation?

Spray polyurethane foam (SPF) provides an R-value of R-6 to R-7 per inch, significantly higher than fiberglass batts or rigid foam boards of the same thickness.

Can PU foam spray be used for cold storage rooms?

Yes, high-density closed-cell SPF is one of the most effective insulation systems for cold stores and refrigeration rooms, providing both thermal insulation and an airtight, moisture-resistant barrier in a single application.

Does PU foam spray also waterproof roofs?

Yes, closed-cell SPF creates a seamless, monolithic barrier that provides both thermal insulation and waterproofing in one application, eliminating the need for separate membrane systems.

How long does spray foam insulation last?

Properly applied and UV-protected SPF insulation typically lasts 20–30 years with minimal degradation in performance.
